when in use and furthermore be of such a is to provide a safety bodiment of .ithe drawings construction as to enable the ready and easily assembling and disassembling of 'the razor. Y

A still further object of the invention is to provide a safety razor of the above mentioned character, which is of such a construction as to enable the blade to be flexed, to a convex position and performing this -function by merely rotating the handle.

A still further object of the invention is to provide a'safety razor of the above mentioned character, which is simple in construction, inexpensive, strong,.durable' and well adapted for the purpose for which it is designated. p

Another important object of the invention razor-of the above mentioned character, which will be flexed together with the flexible guard upon which it is mounted by the action of the handle which is associated therewith. a

Other objects and advantages of this invention will become apparent during the course of the following description.

Figure 3 is alongitudinal section;

Figure f'is a fragmentary plan view of the flexible guard member.

Figure 5 is a top plan view of a modification of my invention. p

Y Figure 6 is a longitudinal sectional view of the same. I 3

-Figure 7 is a transverse section of the modification. v i

In the drawings wherein for the purpose of illustration is shown the preferred emmy invention and mores-particularly with relation to Figs. 1, 2 and 3 of flexible guard and is provided with transverse flanges 2 at the corners of its respective sides. This is more clearly shown in Fig. 1 of the drawings. The transverse threaded for the numeral 1 designates a.

sides are provided with the'usual teeth 3 on the respectlve' edges and the flexible guard 1 is provided with a central aperture 4 for the purpose hereinafter'to be more fully described.

The flexible guard 1 has its upper face provided with a flat surface for the purpose of receiving a flexible blade 5. The underface of the flexible guard 1 is provided at its central portion and extending longitudinally thereof with a thinner portion 6 as more clearly shown in Fig. 2 of the drawings. This is provided by having the longitudinal sides of theflexible guard 1 tapering towards thecentral portion thereof and the ."fiurpose of such a construction will be hereinafter more .fully set forth.

The flexible blade 5 which is adapted to be supported upon the upper flat face of the flexible guard 1 is of the usual construction and is provided with sharpened edges at its opposite side and this blade 5 is adapted to be supported upon the flexible blade 1 and fit underneath of the transverse flanges 2 formed in the corners of the flexible guard 1. The flexible guard 1 is provided or carries therewith on the underface thereof a pair of converging arms 7 and 8 respectively and these, arms 7 and'8 respectively which are secured to the underside of the flexible guard -1 by any suitable fastening means such as solder or the like and are arranged adjacent the transverse sides of the flexible guard 1 and are also secured preferably in the central portion'of the flexible guard 1 as more clearly shown in Figs. 2 and 3 of the drawings. The lower ends of the arms 7 and Bare secured or fastened to a threaded sleeve 9. This sleeve 9 is provided with an internally 1 threaded bore 10 and is adapted to cooperate with the threaded end 11 of a suitable handle This handle 12 has its upper end 11 the purpose above described and the upper end of the handle 12 is adapted to engage the underface of the flexible guard 1 and-furthermore carries a pro]ection 13 which is of less diameter than the handle 12 and'this projection 13 is adapted to extend through the central aperture formed in the flexlble guard 1 and has its freeend adapted to engage the blade 5. I

When the several parts are in assembled position as shown in Fig. 3 of the drawings.

the handle 1 2- is rotated so as to cause the threaded end 11 thereof to cooperate with the threaded sleeve 9 and by this action the upper end of the handle 12 will be 'caused to bear against the flexible guard ,1 and in turn will cause the flexible guard 1 and the blade 5 carried thereon to be flexed into a convex position as shown in the dotted lines in Fig. 3 of the drawings. The blade 5 and the flexible guard 1 having been flexed to theproper position the razor'will then be held ready for use.

in the proper adjusted position and is then A cutting edge is therefore provided on the transverse side of the flexible guard 1 and after the razor has been used it is only necessary to loosen'the handle 1 12 from the threaded sleeve 9 and thereby cause the upper end of the handle 4 and the projection 13 carried thereby to be disengaged from the flexible guard 1 and the blade 5 respectively and thereby enable the several parts of the razor to be easily taken apart andcleaned.

In conjunction with the modified form of razor as shown in Figs. 4, 5 and 6 of the drawings the numeral 15 designates a rigid plate or head which is of a convex formation and centrally supports on the underface thereof a threaded stem 16. A flexible guard 17 provided with transverse flan es 18 similar to the one heretofore descri videdwith a central aperture 19 and carried'on the flexible guard 17 is a blade 20 which is of the same construction as the blade 5 above described and this blade 20 is also provided with a centrally located aperture at 21 which is adapted-to register orme rigid convex plate 1 I A suitable handle 22 is provided at its 'comprlsing a flexible guard provided with upper end with an internally threaded bore 23 for the purpose of permitting the same to receive the free end 0 the threaded stem 16 and the upper end of the handle 22 is adapted to enga e and sit against the underside of the flexible guard 17. After the flexible guard 17 and the blade 18 have been placed 1n proper osition upon the threaded stem 16 the threadied end of the handle 22, is then caused to receive the free end of the threaded stem 16 and by rotatin the same in the pro er direction the flexib e guard and the l e carried thereby are adapted to be flexed into the proper curvature so as to conform with the underface of the convex plate 15. When in this position the blade is held in the proper adjustment for use and after the razor has been used the handle is rotated in the reverse direction to cause the flexible normal at position and thereby permit the several parts of the safety razor to be disassembled for cleaning.

ed is pro- I underface of said ard and the plate to return to their- It is to be noted from the foregoing description' that a safety razor has been rovided wherein a flexible guard and a b ade tion by means of operating the handle upon which the blade and guard are supported and furthermore the simplicity of my device. renders the same very efficient in its operation and does not necessitate the employment of several parts in order to accomplish the results. The safety razor of the above construction can furthermore be procured at the minimum cost and when taken apart can be carried in any suitable casing and can be very easily and quickly placed into operative position.

From the foregoing description of the construction of my improved apparatus, it will be seen that I have provided a simple; inexpensive and eflicient means for" carrying out the objects of the invention, and while I have particularly described the ele-- ments best adapted to perform the functions set forth, it is obvious that various changesinform, proportion and in the minor details of construction may be resorted to without departing from the spirit or any of the principles of the invention.

What I claim as new anddesire to secure by Letters Patent is I 1. A safety .razor of the class described comprisin a flexible guard, said flexible guard having its longitudinal sides tapering towards the central portion of the said guard to form a relatively thin longitudinal porare adapted to be flexed into a convex posisacrificing tion, a blade supported on the'flexible guard,

a handle having its u per end engaging the guard, and means as-a sociated with the said handle and guard for causing the handle to flex theguard into a convex position.

'2. A safety razor of the class described guard, a-projection carried by the upper end of the said handle and extending through the said opening in the said guard and engaging the said blade, and means associated with the handle and the flexible ard for causing the guard and blade to e flexed intov a convex position by action of the handle. g 3

3. A' safety razor of the class described comprising a flexible guard, a. blade,.means at the respective corners of the said flexible. guard for holding the flexible blade in position upon the said guard, a pair of arms secured to the underfa'ce of the said flexible guard and having their lower ends converging and fastened to a threaded sleeve, a

handle provided with a threaded end for 00- having its free end in engagement with the operation with thethreaded sleeve, the upblade, said flexible guard and blade adapted per end of said handle being in engagement to be flexed to a'convex position by rotation 10 with the underfaee of the said flexible guard, of the handle within the threaded 'sleeve.
